Add striping to details column

[hohonuuli]

From Kris:

We'd like the gray/black coloration to carry over to the details column as well, helps differentiate each observation

A tech note: The coloration is done via highlighters in JXTable (from the swingx library). Unfortunately, I tried a bunch of ways to highlight the details column. But when stripping is enabled, the highlighter gets confused and ends up coloring part or all of the entire details column. Which is definitely worse than the current behavior.
